Nowadays, due to the increasing power of diesel engines, especially heavy duty diesel engines, and increasing gas pressure inside the combustion chamber, the forces acting on the engine bearings have dramatically raised. On the other hand, becaus eof the competition in the market, it is necessary to increase the engine bearing life and reduce its failure as much as possible. The engine bearings...

This paper described some mechanical properties of aluminum alloy using agro-waste materials such as sawdust, groundnut shell, and eggshell. The sand-casting method was adopted to produce the with 5, 15, 25, 35% wt. additives. microstructure various samples produced after quenched in water, palm oil, engine oil examined while hardness were determined. result obtained shows that values increased...

Extraction and transportation of oil in the Sea are one of the pollution sources in the Seawater. Caspian Sea contains about 100000 million barrels of oil. It also contains over 35000 millions cubic meter of flue gas. Daily extractions of crude oil and gas and transportation of them are the main pollution sources of the Caspian Sea. Many truck to carry goods and oil tankers to carry oil from po...

Approximately 1.5 billion tyres are produced each year which will eventually enter the waste stream representing a major potential waste and environmental problem. However, there is growing interest in pyrolysis as a technology to treat tyres to produce valuable oil, char and gas products. The most common reactors used are fixed-bed (batch), screw kiln, rotary kiln, vacuum and fluidised-bed. Th...

Increased energy demand and the concern about environment friendly technology, renewable bio-fuels are better alternative to petroleum products. In the present study linseed oil was used as alternative source for diesel engine fuel and the results were compared with baseline data of neat diesel. Performance parameters such as brake thermal efficiency (BTE) and brake specific fuel consumption (B...

In the present study, experimental analyses were conducted by using biodiesel derived from second-generation feedstock. terms of cost and accessibility, feedstock has gained more attention due to its environmental approach. Waste-cooking-oil-derived methyl ester was produced through a transesterification reaction in presence synthesized magnesium zirconate (Mg2Zr5O12) heterogeneous catalyst. Th...

investigations are carried out to evaluate the performance of a low heat rejection (lhr) diesel engine consisting of air gap insulated piston with 3-mm air gap, with superni (an alloy of nickel) crown and air gap insulated liner with superni insert with different operating conditions of crude jatropha oil with varied injection timing and injection pressure.  performance parameters of brake ther...

The protection of the environment and pollution control are issues paramount importance. Researchers today engrossed in mitigating harmful impacts petroleum waste on environment. Lubricating oils, which essential for smooth operation engines, often disposed improperly after completing their life. In experimental work presented this paper, deteriorated engine oil was regenerated using acid treat...

13 Oil wastes produced in large amounts in the processes of oil extraction, refining, and 14 transportation are of great environmental concern because of their mutagenicity, toxicity, high 15 fire hazardousness, and hydrophobicity. About 40% of these wastes contain radionuclides; 16 however, the effects of oil products and radionuclides on soil microorganisms are frequently 17 studied separatel...

Waste oil industry has a great potential use, as 77% oil yield are an untapped waste that still has a high economic value as a base for the oleochemical industry, one of which is β-carotene. The study was conducted to optimize the extraction of carotenoids from Crude Palm Oil (CPO) and Palm Oil Mill Effluent waste (POME) conducted by column chromatography and extraction method with a single enz...
